Sex-like DNA exchange in starving bacteria occurs over 100 times more often than spontaneous mutations
How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity to transfer and incorporate DNA, accelerating genetic reshuffling. The process resembles a primitive form of sexual repr

Does a deeper voice make men more attractive? These researchers have the answer
During puberty, as boys transition into men, the dramatic drop in their vocal pitch has sparked a long-running debate among scientists. Why did such deep voices evolve in the first place? Was it to attract female mates or to intimidate rival men? Or perhaps something else is goin

Gut mRNA tech supercharges vaccine and GLP-1 delivery
From vaccines to gene therapies, mRNA medicines often rely on tiny fat-based particles called lipid nanoparticles, or LNPs, to carry treatments where they need to go. But researchers still face a fundamental challenge: getting those therapies to the organs where they are needed m

Could quitting ultra-processed food boost your mental health?
People with depression who dramatically cut ultra-processed foods experienced notable improvements in their symptoms in a small preliminary study. Researchers suspect healthier eating may benefit the brain partly by reducing gut damage and chronic inflammation.

Alzheimer’s risk gene APOE4 may have a reversible weakness
The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing promising new targets for Alzheimer’s, Parkinson’s, and other n

Caltech physicists finally measure a quantum energy ladder predicted 40 years ago
Researchers have experimentally observed energy patterns that physicists have predicted for about 40 years. By arranging laser-trapped atoms into a quantum simulator, they recreated two different quantum tipping points and watched the atoms fall into the exact energy ratios predi
